passes around the ends of the core, fromV covering any portion of those slots which are between the slots into which theV wire is wound. If, in winding wire upon an armature core into the slots which are spaced relatively closely, the wire portionswhich lie adjacent the ends of the core areV drawn taut, these wire portions will cover portions of the core slots intermediate those slots into which'the wire is being wound'.v Such performance would prevent theguse of all of the winding space availablerin slots which are subsequently to 'bef filled with conductors. When hand winding such a core'the wires must be manipulated so that they are pushed toward thej center of the core in order that the space adjacent the ends of the wound slots will be kept open.Y The present invention provides a winding head which guides the wire, as the core isrotated about an axis at right angles to its own aXis, in sucha manner .that the wire lying adjacent the ends of the core will be kept out of the winding region of othercoils to be wound.

F-urther objects 'and advantages Vof the present invention `will be apparent from the following description, referencebeing had to the accompanying drawings wherein a pre-V ferred embodiment of one form ofthe present invention is clearly shown.

Referring to the drawings, a table 2O which issupported by legs 21 and 22 supports a power driven shaft 23 to which a winding head 24 is attached'.` The head 24 includes a hub 25 providing a recess 26of cylindrical formation for receiving a slotted armature core 27 which is mounted upon a shaft 28. The core 27 is maintained in engagement with the head 24 as shown in Fig. 1 by a block 29 which is rotatably supported by a rod 30 movable endwise through a guide 31 provided by a bracket 3 2 attached Vto the table, 20. A spring 32a housed within the guide 31 urges the block 29 against the core 27. In .order that the block 29 may rotate freely, :an antifriction thrustbearin g 33 is interposed between respectively. These edges are so spaced that i they will coincide with the edges of certain teeth of the armature core in order that the wire will be guided properly by thel plates 40 and 41 into certain spacedcore slots in a manner which is similar to those using armature In order that the wire which crosses-the the core lslots intermediate those into which a coil is wound, the winding head 24 is provided with other wire guiding or camming plates' 44 and 45 having parts 44a and 45a, respectively, which form continuations of the relatively fixed plates 40 and 41, respectively. The plates 44and 45 are provided with portions 44?) and 455 respectively which overlie the ends of the core and provide in effect end walls for the recess 26. A,

Figs. 5 and 6 show the winding of a coil 50 into slots S1 and S7 of the core 27. If the end portions of the coil 50 were drawn straight between the bottoms of the slots S1"v and S7 it is apparent that the ends of the slots S2 and S6 would be covered. This would interfere with winding into these slots during subsequent winding operation. The camming surfaces 445 and 45?) are so constructed andarranged that the wires ofthe coil will be directed against the ends of the core 27 in such a manner as to leave the ends of the slots S2 and S6 open.

` The plates 44 and 45 are yieldingly urged against the ends of the core and the wire which may overlie the ends of the core by springs 52 which pass through holes 53 provided in the hub 25 of the winding head 24. Each end of a spring 52 encircles a lug 54 provided by an arm 55 integral with each of the plates 44 and 45. Each arm 55 is provided with a pair of apertured ears'56 carrying'a pin 57 for supporting a roller 58. Each roller' 58 is engageable with a conical surface 59 of a ring 60. K The ring 60 is attached by bolts 6l to bent plates 62 which together with an intermediate plate 63 provide a fabricated lever 64. The lever 64 is pivoted upon a pin 65 supported by bracket 66 attached to the table 20.v rI he lower end 'of the lever 64 is pivotallyconnected at 67 with a link bar 68 which is clamped by screws 69 and nuts 70 to a link bar 7l.r .The link bar 71 is pivotally connected at 72 with a bell crank levei1` 73 which is pivote'd at 74 upon the leg'2l of the table 20. The screw 69 may pass through round 'holes in onevof the bars 68 or 7l and through slots in the other of these bars in order that an adjustment may be made horizontally between the pivotal connections 67 f and 72. In this way the normal position of the ring. 60 may be adjusted relative to the position of the operating lever 73. If desired, the lever 7 3 may be operated by treadle mechanism not shown.

.Afterwinding a coil upon the core 27, both the levers 37and 73 are pressed downwardly in order to Afree the core from the block 29 and from the winding plates 44 and 45'. When the core is turned to a new position for the next winding operation the lever 37 may be released to permit the springV 32 to move the block 29 into engagement with the core 27 and the lever 73 is released to permit the springs 52 to urge the wire camming plates 44 and 45 toward the ends of the armature core andagainst any windings which may be wound thereon. Since the application of windings to the core may vary the distance to which the wire camming plates 44 and 45 may approach the core before engaging the wires, the plates are not urged in this manner by a non-yielding resistance but by the springs 52 which Asimply move the camming plates 44 and 45 as far as they will move toward the core and then yieldingly press them against the core or the windings which cross the ends of the core.
